Vortex 635ZR-48 CAT5 Red Aluminum Rear Sprocket 530-Pitch 48-Tooth

The Vortex 635ZR-48 is a CAT5 red anodized aluminum rear sprocket featuring a 530 chain pitch and 48 teeth, engineered for motorcycle riders seeking a high-performance, lightweight alternative to a stock steel sprocket.

Vortex's CAT5 process anodizes the aluminum billet first, then CNC machines the sprocket, resulting in a vibrant red finish with contrasting silver highlights on the machined surfaces. The sprocket is manufactured from a specially formulated aluminum alloy per Vortex specifications and is 100% CNC machined in the USA to the tightest tolerances, ensuring a perfectly concentric sprocket every time.

Key Features:

• 530-pitch chain compatibility — designed for OEM 530 applications
• 48-tooth rear sprocket — available in single-tooth increments for precise gearing adjustments
• CAT5 red anodized finish — anodized before machining for a bright color with silver machined highlights
• Lightweight aluminum construction — reduces rotating mass for improved acceleration
• Vortex patented saber tooth groove design — reduces drag and friction for better acceleration and deceleration
• 100% CNC manufactured in the USA — precision machining ensures concentricity and extended chain and sprocket life
• Specially formulated alloy per Vortex specifications for optimal strength-to-weight ratio

Reducing rotating mass at the rear wheel has a multiplied effect on overall performance — less unsprung, rotating weight means the engine works more efficiently, freeing horsepower and improving throttle response. The Vortex 635ZR-48 is an ideal upgrade for sport and performance motorcycle applications running a 530-pitch drivetrain.
